Autotesting

Test Sequence
When the Autotest button is pressed, the following actions occur:
1. The DH will first attempt to communicate with the RH (Remote Handset)
using one correctly wired pair. If it is unable to establish communication, the
DH will display a message that it is looking for the RH and continue trying
until the Autotest is manually canceled or the RH is found.
2. Once communication with the RH is established, its serial number is checked to
see if current field calibration data exists. If a field calibration has not been
performed in the last 7 days with the RH unit, the Autotest will be aborted and
a
Calibration Required message will display.
3. If the serial number is valid, the DH will proceed with the specified Autotest.
The first test performed in most Autotests is the Wire Map for twisted pair
cable types.
4. After running the Wire Map test, Autotest runs the remaining tests specified
for the currently selected cable type. You have the option of specifying (in
Autotest Preferences) that testing halt after any failed test or proceed through
the entire Autotest regardless of test failures.
Note: All tests after Wire Map will only be performed on valid wire pairs.
5. Once an Autotest has been completed, all of the test data can be reviewed,
saved, and printed.
•
The test results for the last Autotest are held in non-volatile memory and
available for review or storage, even after power is cycled off and back on.
•
The last Autotest results remain in non-volatile memory until they are
replaced by new test results or the memory is cleared.
